The Problem

• IT decision makers of enterprise level
  companies face the daunting task of
• Providing a survival IT Platform
• Providing a durable IT Platform
• Providing an adaptable IT Platform
• Providing a compliant IT Platform
• Providing a cost effective IT Platform

3
The Challenge

• Building a true resilient IT infrastructure
  requires significant
• Planning
• Resource allocation
• Underlying CxO / Board commitment

4
a Methodology for Success.

• Fundamental Steps
• SETUP a dedicated IT Infrastructure Resiliency
  Planning Team
• PLANNING is key to defining the Enterprise / Data
  Center Platform Critical Goals
• Develop a fundamental corporate IT Infrastructure
  STRATEGY for achieving the Critical Goals
• Acquire CxO / Board SUPPORT for Team, Goals and
  Strategy

5
PLANNING The Data Center

• Building a true resilient Data Center platform
  requires addressing 4 Fundamental Components
• Capacity Planning
• Floor Plan Layout
• MEP Load Distribution Strategy
• Efficient / Value Based Procurement and
  Infrastructure Deployment

6
Step One Capacity Planning

• Define the current and FUTURE capacity for both
  MEP and DATACOM requirements of the Data Center
• Key Capacity Constants
• 1) One Rack takes up 40 SF of Raised Floor
• 40 SF of MEP Equipment Space
  (Medium Density)
• 2) One 20 amp 120 VAC circuit 2 kW (approx)
• 3) One Single Phase 30 amp 208 VAC circuit
  5.77 kW
• 4) BTUs kWh 3,412
• 5) One Ton of Cooling 12,000 BTUs per Hour
• Example One (1) 20 Ton CRAC provides cooling
  for 80 kW of
• electricity i.e. 20 racks _at_ 4 kW/
  Rack

7
Step One Capacity Planning

• KEY CAPACITY VARIABLES
• Total Data Center Floor (in SF)
• Kilowatts per Rack (kW / Rack)
• Production Balance ( of Total Load _at_ each
  facility)
• Production Capacity Processing Storage (MIPS
  / TB)

8
Step One Capacity Planning

• KEY CAPACITY FORMULAS for Current and Future
  MEP and DATACOM Requirements
• 1a CURRENT (Data Center Floor) Existing DC
  Foot Print 1.2
• 1b CURRENT (Kilowatts per Rack) Existing kW
  per Rack 1.2
• 1c FUTURE (Data Center Floor) Existing DC
  Foot Print 2.0
• 1d FUTURE (Kilowatts per Rack) Existing kW per
  Rack 2.0
• 1e CURRENT (Bandwidth) Existing Bandwidth
  1.4
• 1f FUTURE (Bandwidth) Existing Bandwidth
  10.0
• 1g FUTURE (Load Dispersion / Site)
  Existing Production 0.33
• 1h FUTURE (Production Capacity / Site)
  Existing Production 4.0

9
Step One Capacity Planning

• EXAMPLES
• 1a IF CURRENT (Data Center Floor) 2,000 SF
  48 Racks
• THEN near term growth will most likely exceed
  2,400 SF 60 Racks
• AND long term growth will require a minimum of
  4,000 SF 80 Racks
• 1b IF CURRENT (Kilowatts per Rack) 3.0 kW per
  average rack usage
• THEN near term growth will most likely exceed
  3.6 kW per rack
• AND long term growth will require a minimum of
  6.0 kW per rack
• 1e IF CURRENT (Bandwidth) 1.5 Gigabits per
  Second (GBS)
• THEN near term growth will most likely exceed
  3.0 GBS
• AND long term growth will require a minimum of
  15.0 GBS
• 1g IF CURRENT (Production Load) 100 MIPS / 4
  TB _at_ one Site
• THEN long term CAPACITY PLANNING should assume
  a LOAD BALANCED platform of 3 sites capable
  of 400 MIPS/ 16 TB per site

Step Two Floor Plan Layout

• KEY DESIGN CONCEPT Compartmentalize
• Define the specific Floor Plan based on
  PRIORITIES
• Security / Access and Control Parameter
• Power / Cooling (Heat Dissipation) Densities
• Business Unit

11
Step Two Floor Plan Layout

• EXAMPLES
• Security / Access and Control can be addressed
  through multiple levels of physical separation
• Highest Level Separate Rooms with 4 hour fire
  walls and Man Traps
• Medium Level Physically demised rooms using
  bonded drywall with a wire fence center from slab
  to ceiling
• Moderate Level Steel Cage demising each
  specified Business Unit from slab to ceiling

12
Step Two Floor Plan Layout

• EXAMPLES
• Power Densities can be addressed through 3
  physical zones
• High Density Racks requiring in excess of 10 kW
  - Specifically focused on supporting Blade
  Chassis Chilled Water infrastructure required
• Medium Density Racks requiring 6 to 10 kW
  Blade Servers, Storage Devises Significant
  increase in SF allocation per rack for
  under-floor air-cooled distribution
• Moderate Density Racks requiring 2 to 6 kW
  Light Server distribution, Tape Devices, Network
  Devices Traditional under-floor air cooling
  acceptable

13
Step Three MEP Load Distribution

• KEY STARTING POINT Defining the MEP Fork in
  the Road Under floor air cooling vs. in-row
  chilled water based CRAC systems.
• Rack densities (in excess of 6 10 racks)
  requiring 8 kW /rack will require a chilled water
  based CRAC system
• Three Build Options to supporting High Density (8
  kW / Rack )
• CHEAP and SHORT-SIDED Spread out rack based
  devices to lower energy consumption per rack
• EXPENSIVE and COST INEFFICIENT Build the Data
  Center with a chilled water based MEP
  infrastructure to support in-row cooling
• REASONABLE Separate LOW / MEDIUM Density Racks
  into a separate MEP ZONE (/ room) from HIGH
  DENSITY Racks

14
Step Four Efficient / Value Based Procurement
and Deployment

• KEY Efficient and Cost Effective components to
  building a better IT Data Center Facility
• Build / lease (w/option) facilities with adequate
  physical shell space to support future expansion.
  
• Physically separate High Density Racks that
  require expensive in row based chilled water
  solutions from Medium / Moderate racks that can
  be cooled with traditional under floor air
• Look carefully at developing a load balanced /
  mirrored multi-site platform vs. a one on-site
  production facility with an off-site D/R
  facility
• NOTE COST OF MOVING A PRIMARY PRODUCTION SITE
  AT A LATER DATE IS AN EXTREME EXPENSE AND
  SIGNIFICANT DISRUPTION
• Only enter in Datacom contracts that provide
  roll-up options to more bandwidth at
  substantially lower cost per unit at a future
  date.
• 5. Build networks that provides scalable /
  gigabit (lambda) bridges to key metro NAPs
